Baba Yaga is an old hag who lives in a house built on chicken legs and kidnaps small children. She is one of the most pervasive and powerful creatures in all mythology. But what does she have to do with a writer's journey to Bulgaria in 2007 on behalf of her mother? Or with a trio of old women who decide to spend a week together at a hotel spa? Startlingly original, "Baba Yaga Laid an Egg" takes a traditional myth and spins it afresh. The result is an extraordinary meditation on femininity, ageing, identity, secrets, storytelling and love.
